Very cool concept. It really does look nice. Always cool to see what you can do on a budget. Impressive.
Thanks. I simply see no reason a basic setup needs to cost upwards of $300!
I like the graphs to. Thanks for the comment and yes I love cheap as well.
This is great, I love the graphs. I'll be keeping an eye on your thread. I love cheap.
awesome concept and I'm digging it!
Thanks! I have Friends looking for jobs, degreed people working as waitress, live paycheck to paycheck you name it. People just don't have the beans to pour into a hobby. Why not? lol
Please do tell more about the CO2 setup. Those are old paint ball gun regulators?
I'd love to. I picked up a valve and fully filled Oz. tank this morning for $20! Guess my 55g gets pressurized!
These are images and explanations of those parts I bought this morning.
Below is a standard ASA on/off valve. This screws on top of your paint ball CO2 tank. Notice the two holes on the side? This is where CO2 exits at the tank PSI. This being the system's drawback to a regulator. The needle valve you use must be of high quality to meter so low at high pressures. However, I can obtain 1 drop per second with the valve I bought from Lowe's. That's pretty much the bottom end of my injection techniques.
One of the things that bother me about other examples of this are that pressure gauges should be added. They say one side for the needle valve and the other with a gauge. Paint ball tanks are liquid CO2. This means the pressure will remain essentially the same until the liquid runs out. When that happens the pressure falls quickly. To know how much is left, you need to measure the tank. Now you understand why they measure tanks sizes in ounces. Ignore the gauge! Instead use the other hole for another tank, bigger setup, or cap it.
This is the bottom of the valve. This screws onto your CO2 bottle. When the top knob is turned clockwise the silver pin compresses the CO2 bottle pin letting gas flow .
This is the valve disassembled. The silver pin at the bottom that has an 'O' ring. If your valve leaks from the knob replace this 'O' ring. To remove just unscrew the handle. Push the needle out of the bottom.
Valves and tanks screw together. Here is another place for the valve to leak. The 'O' ring on the tank should be free of defects. Just replace them frequently. A box costs $2 or so.
This is the needle valve from Lowe's. I like this one because the handle of the valve is parallel with the valve making it easier to turn.
Exact size and model number. The valve fitting is 1/8" and the tubing is 1/4".
Use teflon tape on the tank side of the valve. Don't forget to tighten the handle nut. They come loose and will blast gas out until tightened.
Now just attach your tubing to the valve and enjoy.
